After watching his wife suffer adverse reactions to her usual skin-care regimen during her first pregnancy, Antony Buck and his business partner, Robert Calcraft, created a natural line using only pure plant- and mineral-derived ingredients. Founded in 2000, REN, Swedish for “clean,” is a luxurious collection of creams, balms, serums, and oils made without synthetic fragrances, parabens, or sulfate detergents. Brand-favorite Moroccan Rose Otto Body Wash uses steam-distilled rose otto oil, a nutrient-rich soothing agent that is excellent for dry, sensitive, or aging skin.
